National has managed to win praise from many of its usual critics for its latest policy to try to lift student achievement - even the teacher unions have refrained from strong criticism of the plan to pay the best teachers and principals more to help colleagues or struggling schools.
So far the strongest criticism has been from the primary teachers' union, the NZEI, whose President Judith Nowotarski said similar policies overseas had failed, and there was a risk "parachuting" principals into struggling schools could result in a climate of competition instead of co-operation.
She said there were other areas that the $395 million new funding could have been put towards, such as helping students with special needs, and criticised National for failing to work with the unions on that policy.
However, she said the NZEI did welcome the recognition of the importance of quality teaching.
She was reluctant to liken it to performance pay, but said the new positions differed from the union's preference of a new grade for expert teachers on a higher salary which the union was talking to the Ministry of Education about.
